Instructions

In this experiment, you will see 5 letters at the same time. You need to respond to the one in the middle only.

If you see an X or a C in the middle, tap the LEFT side of the screen.

If you see a V or a B in the middle, tap the RIGHT side of the screen.

For example, if you see the letters XXCXX, you tap the LEFT side.

Note: You need to get used to the task. Before the flanker effect can work, you need some practice. The flanker effect might not occur until you have done this task a few times.

If you respond correctly, the fixation cross will turn green; wrong responses or responses that are too slow will lead to a flashing red fixation cross.

You have 2 seconds to respond on each trial. There are 50 trials.
